Calculate Custom Row Subtotal in Matrix Visual

Hi ZiyadSyauqi ,

Thanks for the reply from ridhoaryo24  / amitchandak .

Please try:

Enter Power Query and pivot the Attribute column:

This is the data after pivoting:

Exit Power Query and create a measure:

Measure = 
VAR _tm = SUM('Table'[tm_actual])
VAR _lm = SUM('Table'[lm_actual])
RETURN
IF(
    HASONEVALUE('Table'[group_metrics]),
    DIVIDE(SUM('Table'[tm_actual]),SUM('Table'[lm_actual])),
    DIVIDE(_tm,_lm))

After creation, set the format:

Drag the following fields to the Matrix visual object:

The final page effect is as follows:

Thanks using some additional DAX code and combine with your solution i got this solution:

ValueNew = 
VAR lm_actual = CALCULATE(
    SUM(Table[Value]),
    Table[Attribute] = "lm_actual",
    ALLEXCEPT(Table, Table[group_metrics], Table[metrics])
)

VAR tm_actual = CALCULATE(
    SUM(Table[Value]),
    Table[Attribute] = "tm_actual",
    ALLEXCEPT(Table, Table[group_metrics], Table[metrics])
)

VAR lm_group = CALCULATE(
    SUM(Table[Value]),
    Table[Attribute] = "lm_actual",
    ALLEXCEPT(Table, Table[group_metrics])
)

VAR tm_group = CALCULATE(
    SUM(Table[Value]),
    Table[Attribute] = "tm_actual",
    ALLEXCEPT(Table, Table[group_metrics])
)

RETURN 
SWITCH(
    TRUE(),
    SELECTEDVALUE(Table[Attribute]) = "vs_n_min_1_pct" && HASONEVALUE(Table[metrics]),
            DIVIDE(tm_actual, lm_actual, 0),
    SELECTEDVALUE(Table[Attribute]) = "vs_n_min_1_pct" && NOT HASONEVALUE(Table[metrics]),
            DIVIDE(tm_group, lm_group, 0),
    SUM(Table[Value])
)
